Sash lock template



March 7, 1967 w. H. DEACON, SR 6 SASH LOCK TEMPLATE Filed May 26, 1964 United States Patent 3,307,268 SASH LOCK TEMPLATE William H. Deacon, Sr., 1041 Marengo Ave., Forest Park, Ill. 60130 Filed May 26, 1964, Ser. No. 370,208 Claims. (Cl. 33189) This invention relates to sash lock templates adapted for accurately gauging and starting the screw holes for attachment of sash locks on wooden window sashes.

When installing sash looks, it is important to have the separable latch and keeper units properly oriented with respect to each other on the check rails in order to secure optimum locking efficiency. Some sash lock manufacturers provide paper templates for guidance in making the screw holes for mounting the separable sash lock parts. Such paper templates still require a fair degree of skill on th part of the carpenter or other person installing the sash lock for attainment in accuracy of spotting and driving the mounting screws. Where no paper template is provided, scratch awls, punches, pencils, drill points, and the like may be employed to spot the screw holes in the sash lock parts, but always the element of skill of the installer is of the essence to attain accurate results for such prior expedients.

An important object of the present invention is to provide a new and improved sash lock template construction which eliminates all need for skill in mounting sash locks and which will afford accurate placement of the mounting screws for the sash lock components.

Another object of the invention is to provide a new and improved sash lock template which as an incident to spotting mounting screw locations for a sash lock also provides starting holes for the screws.

A further object of the invention is to provide a new and improved sash lock template which upon being placed in position on the check rails of a window is adapted to be struck with an impact tool to afford proper spotting as well as starting of screw holes for the mounting screws of sash locks.

Still another object of the invention is to provide a new and improved sash lock template having novel guide means.

A still further object of the invention is to provide a new and improved sash lock template adapted to be constructed from inexpensive material and having a thoroughly reinforced construction for effectively withstanding application of an impact or driving tool thereto.

Other objects, features and advantages of the present invention will be readily apparent from the following detailed description of a preferred embodiment thereof, taken in conjunction with the accompanying drawing, in which:

FIGURE 1 is a front elevational View of a sash lock template embodying features of the invention;

FIGURE 2 is a bottom plan view of the template; and

FIGURE 3 is an end elevational view of the template.

A sash lock template 5 according to the present invention comprises an upstanding fin-like body 7 having substantially coplanar oppositely extending foot flanges comprising a rear flange 8 and a front flange 9. A practical, inexpensive construction comprises forming the device from suitable gauge sheet metal such as cold rolled steel sheet or strip in which the body portion 7 comprises a folded and thereby double thickness structure provided with a rear wall 7a and a front wall 7b from which the flanges 8 and 9, respectively, extend integrally in one piece. In the illustrated form, the body portion 7 and the flanges 8 and 9 are longer than the sash lock for which the template has been provided and the total width of the area covered by the flanges 8 and 9 is greater than that covered by the sash lock hardware.

3,307,268 Patented Mar. 7, 1967 "ice For spotting the screw holes for the keeper component of the sash lock on a check rail A on the lower part of the upper window sash, a pair of downwardly extending combination spotting and screw hole starting prongs 10 is provided on the rear foot flange 8. For spotting screw holes for the latch portion of the lock to be mounted on a check rail B at the top of a lower window sash associated with the upper window check rail A, downwardly extending combination spotting and screw hole starting prongs 11 are provided on the front foot flange 9. In each instance, the prongs 10 and 11 are desirably rivet headed pins with the heads riveted to the respective foot flanges which are provided with suitable apertures 12 therethrough for this purpose. Each of the spotting prongs 10 and 11 has a sharp conically tapered penetration tip 13.

While the spotting prongs 10 and 11 are properly related to each other for accurate relative positioning of the components of the sash lock, it is further required for effective installation that the sash lock components be properly located in respect to the adjacent edges of the check rails A and B. For this purpose, a downwardly projecting guide flange 14 is provided on the template in a plane between the adjacent proximal ends of the foot flanges 8 and 9. At its lower edge the guide flange 14 extends below a plane across the tips of the points 13 whereby the guide flange can be inserted in a gap G (FIG. 2) which may, if necessary, be forced by pressing the lower margin of the guide flange downwardly between the check rails. To facilitate this such lower margin of the flange 14 is slightly tapered as shown at 15 (FIG. 3). There is usually suflicient tolerance in the 'window assembly including the supporting frame structure to permit the gap G at least partially, and since the sash lock is generally placed as nearly as practicable centered on the check rails, the check rails will yield slightly bendably sufficiently to ease the flange 14 downwardly therebetween without damage, if unusually close tolerance is found.

In addition to serving as a guide flange, the flange 14 also provides reinforcement for the body frame 7. For this purpose the flange comprises a plate which extends upwardly into the fold between the opposing walls defining the body 7 and with its upper edge abutting or at least quite closely adjacent to the underside of the crown or ridge of the body. Suitable means such as rivets 17 secure the flange plate 14 firmly between the body walls.

In using the template 5, it is located at the desired position intermediate the lengths of the check rails A and B, generally nearly as practicable centered, and the tapered margin 15 of the guide flange 14 inserted between the check rails A and B until the points 13 of the spotting and screw hole starting prongs 10 and 11 engage the upwardly facing surfaces of the check rails. Then by striking the crown ridge of the template body 7 substantially centrally with an impact tool T such as a hammer, the points 13 will be driven into the respective check rails and the prongs will form screw starting holes. As will be observed in FIGURE 1, suitable indicia means such as a mark, symbol, or legend 18 is desirably provided to identify the front of the template 5 so that the rear flange 8 will be properly placed over the upper window sash check rail A and the front flange 9 will be properly placed over the lower window sash check rail D. Thereby, the spotted and started screw holes will be properly located when impressed by the prongs 10 and 11. As will be observed in FIGURES 2 and 3, there is a slightly different relative positioning and spacing of the two sets of prongs 10 and 11 to accommodate variance in the placement of the respective screw holes in the keeper and latching components of the sash lock.

In order to facilitate withdrawal of the prongs 1i) and 11, it will be observed that they are tapered toward the tips 11. Further, the body portion 7 of the template extends upwardly to a suflicient height to afford desirable purchase and grip thereof between the fingers of the users hand under a handle bulge 19 above the rivets 17 which are disposed as close as practicable to the junctures of the flanges 8 and 9 to the respective wall portions of the body 7. Thus, even though the prongs 10 and 11, which in a practical construction may be about inch long, may be driven all the way into the check rails, pulling the template 5 free after driving can be effected with minimum resistance. Further, it will be observed that by having all of the prongs 1t and 11 of equal limited length and substantially identically formed as to diameter and taper, uniform gauging of the size and depth of the screw starting holes is accomplished.

It will be understood that modifications and variations may be effected without departing from the scope of the novel concepts of the present invention.
